Gravitational Microlensing by the MACHOs of the LMC
نویسنده
چکیده
The expected microlensing events of the LMC by the MACHOs of the LMC itself are calculated and compared with analogue events by objects in the Galactic halo. The LMC matter distribution is modelled by a spherical halo and an exponential disk while a face-on exponential disk is used for the stellar distribution of the LMC. Among the microlensing events discovered by the MACHOs and EROS projects, a fraction of 22% could be caused by the lenses near the center of the LMC or 13% from lenses at 5o from the LMC center. Therefore, any statistical study of these microlensing events must take the LMC lenses into account. ———————————————————————– Subject headings: gravitational lensing – galaxies: Magellanic Clouds

Magellanic Cloud Gravitational Microlensing Results: What Do They Mean?
Recent results from gravitational microlensing surveys of the Large Magellanic Cloud are reviewed. The combined microlensing optical depth of the MACHO and EROS-1 surveys is τLMC = 2.1 +1.3 −0.8 × 10 which is substantially larger than the background of τback ≤ 0.5 × 10 −7 from lensing by known stellar populations although it is below the expected microlensing optical depth of τ = 4.7 × 10 for a...
متن کاملSpatially varying mass function of MACHOs in the galactic halo and interpretation of microlensing results
The gravitational microlensing experiments in the direction of Large Magellanic Cloud (LMC) predict a large amount of white dwarfs (∼ 20%) filling the galactic halo. However, the predicted white dwarfs have not been observed at the galactic halo. To interpret the microlensing results and resolving the mentioned problems, we use the hypothesis of spatially varying mass function of MACHOs, propos...
متن کاملMicrolensing Events of the Lmc Are Better Explained by Stars within the Lmc than by Machos
The recently reported microlensing events of the LMC have caused much excitement, and have been interpreted as due to ‘dark objects’ (MACHOs) in the halo of our Galaxy. It is shown here that the stars within the LMC play a dominant role as gravitational lenses and can indeed account for the observed events. For observations within the bar of the LMC, the probability of microlensing being caused...
متن کاملLensing Budget in the Dominate Brown Dwarfs of Halo: A Possible Solution for the Microlensing Problems
For searching gravitational microlensing events, millions of stars in the Large Magellanic Cloud (LMC) have been monitored for one decade and only a dozen of events have been detected. The low number of events causes ambiguities in studying the mean mass of MACHOs and their contribution to the Milky Way halo mass due to Poisson fluctuation. The results obtained by the microlensing experiments, ...
متن کاملStatistical Interpretation of LMC Microlensing Candidates
After a decade of gravitational microlensing experiments, a dozen of microlensing candidates in the direction of the stars of the Large Magellanic Cloud (LMC) have been detected by the EROS and MACHO groups. Recently it was shown that the distribution of the duration of the observed LMC microlensing events is significantly narrower than what is expected from the standard halo model. In this art...
